5.3.4 EUT Power, Power source for the EUT
To connect the EUT Power 1 Input with the public power supply please cut the three black, blue and
green/yellow cables supplied into two halves of the same length. One half used for the EUT Power 1
connection on the rear side of the TRA3000 F-S-D-V-C, and the other half for supplying the EUT from the
front panel. The high inrush current during the DIPS test can only be reached, when the public power
supply can deliver 500 A peak current. The public power supply must be protected by 16 A fuse.
Connection of the internal Variac:
The Bridge 1 connects the internal variac with the public power supply on the primary side.
The Bridge 2 connects the secondary side of the variac to the EUT power 2 input.
Attention: Phase and neutral must be connected correctly. When the phase and the neutral are connected
correctly, this is indicated on the front panel by a green LED.
Attention!
If your power supply is equipped with fault current protective switch it may release when
connecting the TRA3000 F-S-D-V-C. A high current will flow to earth when Surges are
superimposed between phase and earth. The impedance of 2 Ohm in series with 10 Ohm and 9 µF
is a load on the power supply.
